"By comparing MRI scans with psychopathy assessment results, the researchers found that a larger striatum was linked to a stronger need for stimulation, including thrill-seeking, excitement, and impulsive behavior. In the published study, stimulation-seeking and impulsivity partly explained the relationship between striatal volume and psychopathy, accounting for 49.4 percent of the association. Professor Adrian Raine from the Departments of Criminology, Psychiatry, and Psychology at University of Pennsylvania, who co-authored the study, said: "Because biological traits, such as the size of one's striatum, can be inherited to child from parent, these findings give added support to neurodevelopmental perspectives of psychopathy -- that the brains of these offenders do not develop normally throughout childhood and adolescence."" https://www.sciencedaily.com/releases/2026/05/260510030946.htm
